Abstract

The use of Black Soldiet Fly (BSF) in processing organic waste offers numerous benefits, including significant waste volume reduction, transformation of waste into value-added products such as organic fertilizers, livestock feed, and fish feed, as well as supporting the implementation of a circular economy. However, organic waste processing practices in BSF larvae or what is more widely known as maggot with maggot houses often face challenges, particularly in terms of funding. Financial factors are crucial elements that determine the operational sustainability of such waste management systems. This study aims to analyze the financial conditions and operational feasibility of Rumah Maggot Cimincrang and Imah Maggot Bantaran. The study employs the Net Present Value (NPV) method, which calculates the present value of total net revenues after deducting costs over a specific period. NPV serves as a tool to assess the financial feasibility of an activity. If the NPV is positive, the activity is considered financially feasible and profitable. The results indicate that the operational feasibility of Rumah Maggot Cimincrang can be achieved through product diversification, such as producing maggot meal and maggot oil, alongside optimizing marketing efforts via digital platforms like e-commerce with a NPV of IDR 161,769,698. Meanwhile, Imah Maggot Bantaran, which operates on a community-based model, is already financially viable with an NPV of IDR 4,333,190,208. However, further efforts are needed to enhance operational consistency, ensuring the production of sustainable products over the long term.

Abstract

Population growth and metropolitan activity in Cimahi City, with a population of 598,698 residents in 2024, and with a waste composition dominated by organic materials, have heightened the need for a more effective waste management system. Sarimukti Landfill, which serves as the regional disposal site for Greater Bandung, has exceeded its capacity, requiring compliance with disposal capacity limits within its service coverage. Given the limited land availability and high population density, optimizing existing waste management facilities has become the most relevant and feasible strategy. This study aims to formulate sustainable waste management strategies for Cimahi City by identifying strategic factors using the SOAR framework. Data were collected through semi-structured interviews and direct observations with stakeholders involved in waste management in Cimahi City. The SOAR approach was selected to explore strengths, opportunities, aspirations, and expected results, thereby producing a strategic mapping that emphasizes stakeholder collaboration. Based on the SOAR analysis, the Strength–Aspirations (SA) strategy demonstrates the greatest implementation potential, comprising efforts to strengthen waste-sorting literacy and practices, develop standardized SOPs, enhance inter-agency coordination, innovate volume-based financing schemes and digital service channels, and reorganize operational systems toward sustainability.
